We're dividing 686331 by 84 
We want to divide 686331 by 84.

Going ahead to step 1:
84 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 84

Step 2:
84 can be fit into 68 0 times, resulting in a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Fetch the next digit (6) from the dividend, attach it to 68 and continue: 686 / 84

Step 3:
The number 84 fits into 686 8 times, leaving a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 672 from 686 leaves us with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 84

Step 4:
When dividing 143 by 84, we get 1 with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 81.0
If we take 84 away from 143, we end up with 59.
Fetch the next digit (3) from the dividend, attach it to 59 and continue: 593 / 84

Step 5:
84 can be fit into 593 7 times, resulting in a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 817.0
If we subtract 588 from 593, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 84

Moving on to step 6:
When dividing 51 by 84, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 8170.0
Subtract 0 from 51 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
If we divide 510 by 84, we get 6 and a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 8170.6
Deduct 504 from 510 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
84 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 8170.6
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
If we divide 600 by 84, we get 7 and a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 8170.607
If we take 588 away from 600, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
84 goes into 120 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 8170.6071
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
84 goes into 360 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 8170.60714
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
84 goes into 240 2 times with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 8170.607142
Subtract 168 from 240 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 13:
84 can be fit into 720 8 times, resulting in a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 8170.6071428
Deduct 672 from 720 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
84 can be fit into 480 5 times, resulting in a remainder of 60.
The next digit of our result is 5. 
Result so far: 8170.60714285
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 8170.60714285, with a leftover of 6e-08.
